PAPER-FOLDING MACHINE.

SPECIFICATION forming part of Letters Patent No. 551,918, dated December24, 1895. Application filed April 26, 1895. Serial No. 547,225- (Nomodel.)

paper-folding machine of the kind shown and described in Letters PatentNo. 497 ,7 45, granted to me May 16, 1893.

One object of my invention is the production of a pasting apparatusdesigned to apply paste to the moving sheet of paper by means of atraveling thread or cord, which takes up paste in the cup, carries itout of the cup and delivers it to the sheet, whereby I avoid the leakageof paste incident to slotting the bottom of the cup and arranging a diskto revolve in said slot.

Another object of my invention is the production of an automatic devicefor holding the paste-cup elevated at all times except while a sheet ofpaper is passing over the firstfold rollers, whereby saidfolding-rollers are prevented from being smeared should the feeder misssending a sheet through the machine.

Another object of my invention is to provide an automatically-actuatedpaper-brace for holding the folded papers in an upright position on therack while the fly is back in position to takea folded paper from the delivery-tapes.

The invention will first be described in connection with theaccompanying drawings and then pointed out in the claims.

Figure 1 of the drawings is a perspective view of my improved pastingapparatus. Fig. 2 is a side elevation of such parts onlyof afolding=machine as are necessary to illustrate the application andoperation of the device for holding the paste-cupup out of operativeposition except while a sheet of paper is passing through the machine.Fig. 3 is an end view of the same, showing a sheet of paper passing overthe first-fold rollers and the past ing apparatus in operative position.Fig. 4 is a broken perspective view illustrating only so much of themachine as is necessary to show the operation of the paper-brace withrelation to the fly, the brace being shown in the elevated position.Fig. 5 is a view similar to Fig. 4:, with the paper-brace lowered intooperative position. Fig. 6 is a detail plan view of the fly-actuatingarm and its operating-cam.

In the accompanying drawings, A represents the paste-cup, which may beof any desired shape, but preferably of the form shown. In this cup, ashort distance above its bottom, is journaled a roller 1, and dependingfrom the bottom of the cup, on its outer side, is also journaled anotherroller 2, having a shallow annular groove To the rear wall of the cup,near its upper edge, are secured two standards 4:, in which is journaledanother similarly-grooved roller 5; and to the front wall of the cup,near its upper edge, are also secured two standards 6, in which isjournaled another roller 7, which I prefer to construct in the form of aspider having four arms grooved in their outer ends.

8 represents an endless thread or cord passed over said rollers 1, 2,and 5, and also over the arms of the spider 7, said thread or cord beingmoved in the direction indicated by the arrows when roller 2 is infrictional contact with the moving sheet of paper in the machine. Itwill thus be seen that when the cup containing paste is lowered to theoperative position, as in Fig. 3, the cord will take up the paste, carryit up over the spider, and then down outside of the cup and apply it tothe sheet. As the cord, after taking up the paste, comes into contactwith nothing but the arms of the spider it will be apparent that but aslight quantity of the paste will be removed from the cord prior todelivery to the sheet.

Referring to the drawings, B represents the feed-board; O and D, twoseries of feed-pulleys; E, an idler-pulley; F, a tape-roll; G, a

series of tapes passing over pulleys O and 1),

idler-pulle3 E, and tape-roll F; H, the .firstfold rollers; I, thesecond-fold rollers; J, the third-fold rollers; K, the fourth-foldrollers; L, the shaft from which the first and third fold-rollers H andJ are operated; M, a cam secured on said shaft; N, a lever carrying afriction-roll n on its lower end adapted to invention, which relates tomeans for holding lever N out of operative contact with cam M at alltimes except while a sheet of paper is moving over the first-foldrollers.

R is one of the longitudinal frame-rails of the machine, to which isremovably secured a clamp, S having a laterally-proj ecting stud s.

T is what I term a lever-trip, which is made of a single piece of wire,bent at one end to form a hook 9, and a suitable distance from said hookI form a coil 10 adapted to fit loosely over the stud s on clamp S, thusleaving a straight stem 11. After forming this coil I provide a weightedportion 12 by extending the wire laterally a suitable distance beyondthe coil, and then making a return-bend and carrying the free end in theopposite direction considerably beyond the pivotal point to formwhatIterma finger 13, all as clearly shown in Fig. 2, the constructionbeing such that when the trip is pivoted on the stud s the finger willoccupy an inclined position along the first-fold rollers in thedirection of the rear of the machine, the free end of the finger lyingslightly above the tapes G over said rollers,

and that portion of the trip lying forward of the pivotal point andhaving the return-bend will more than counterbalance that portion of thefinger lying to the rear of the pivotal point, with the result that thestem will normally occupy a vertical position with its hook directlyunder the lever N, so as to hold the latter out of operative contactwith cam M- that is to say, when the highest portion of the cam is underthe lever the hook will engage with the latter and prevent it from beingfurther operated by the cam.

From the above description it will be understood that as a sheet ofpaper being fed into the machine is carried rearward by the tapes itwill come into contact with and press upon the finger 13 of the trip,bearing it down and passing over it. This movement of the finger willswing the stem forward, thus withdrawing the hook from under the lever,all as clearly shown in dotted lines in Fig. 2, when the lever will befree to follow the cam and lower and raise the paste-cup. Should thefeeder at any time fail to send a sheet through the machine the weightedportion of the trip will throw the hook under the lever, where itwillremain until a sheet 14 is passed through to actuate the finger andthus withdraw the hook.

I will now describe the third part of my invention, which consists ofthe paper-brace and its coacting mechanism.

U is the paper-rack.

V is the fly, whose shaft o is journaled in brackets 15 extending fromthe lower transverse frame-rail 16 0f the machine.

W is the revoluble shaft that carries the delivery-tape pulleys w andtapes 10. On this shaft is a fixed bevel-gear 10 provided on one sidewith a cam 17.

V is an arm, bifurcated at one end, and provided with two lateral lugs18 and 19, the other end of the arm being pivoted to a crank 41 fixed onthe fiy-shaft. The bifurcated end of arm V straddles shaft NV, and itslugs are alternately engaged by cam 17, in a manner to impartoscillatory movement and thereby rock the fiy-shaft. Qn the outer end ofthe fly-shaft there is looselypivoted a pawl 20, which engages with aratchet 21 on a shaft 22 for the purpose of moving the rack, all ofwhich parts are shown and described in my former patent above alludedto.

The paper-brace consists of a rectangular wire frame X, the rear ends ofwhich are pivoted respectively in a standard 23, secured to frame-rail16 and in the longitudinal framerail 24. To the front of the frame X arerigidly secured two vertically-depending bracearms at, and in one sideof the frame X there is formed abend 25, on which acts a cam 10 securedon shaft IV, in such manner as to raise the paper-brace out of the wayof the forwardly-moving fly, the paper-brace dropping by gravity whenthe cam has passed out of contact with it.

In operation the brace will drop behind the fiy when the latter is inits forward position and remain against the folded papers on the rackuntil the fiy has gone back, received another paper, and is againreadyto advance, when the paper-brace will move out of the way. By meansof the brace-arms the folded papers will be prevented from slippingbackward at the bottom, this backward slipping of the papers being aninherent defect common to all other paper-braces with which I amacquainted. It will be understood that as the fly goes back its rods Q2willpass on each side of the brace-arms.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. In a vertically-reciprocating pasting apparatus, a paste-cup, afriction roller .journaled beneath and carried by the cup, a rollerjournaled within the cup, a roller and a spider journaled above thecup,.and an endless cord passed under the inner roller, and over theouter rollers and over the spider, substantially as described.

2. In a newspaper folding machine, the combination, with apaster-act1iating lever and a cam by which said lever is operated, of apivoted trip having a hook adapted to normally hold the lever out ofoperative position with relation to the cam, and also having a fingerprojecting slightly above the tapes over the first-fold rollers, theconstruction and arrangement being such that a sheet of paper passingthrough the machine will depress the finger and swing the hook out ofcontact with the lever.

3. In a newspaper folding machine, the combination, with apaster-actuating lever and a cam by which said lever is operated, of awire trip, the wire being bent at one end to form a hook, then bent intoone or more coils, thence carried laterally and given a return bend toform a straight finger extending in the opposite direction, the coilbeing passed over a fixed stud to form a pivot, the hook restingnormally under said lever, and a portion of the finger lying above thetapes over the first-fold rollers, whereby as a sheet of paper is passedthrough the machine the finger will be depressed, and the hook swung outof contact-with the lever, the trip swinging into its normal position bygravity when the sheet has passed through the first-fold rollers.

4. In a newspaper folding machine, the combination, with the paper-rack,the fly, and the shaft carrying the delivery-tape rolls and providedwith a cam, of a paper-brace comprisinga rectangular frame pivoted atits rear end to fixed parts of the machine and having a bend in one sideadapted to be engaged by said cam to elevate the brace, and brace-armsrigidly secured to the front of the frame, the whole being so arrangedthat as the fly moves forward with the paper the paper-brace will beelevated and remain in that position until the fly has deposited thepaper on the rack, when it will drop by gravity and hold the foldedpapers upright until the fly swings back, takes another paper, and isready to deliver it. I

In testimony whereof I affiX mysignature in presence of two witnesses.
